Abstract

In this work, we will share the main results achieved with a Long Wave Infrared (LWIR) Light Field (LF) imaging system with two novel capabilities relevant to IR image science applications: The capability of digitally refocusing to any nearby object planes with a high Signal to Noise Rat io (SNR), this is, to achieve refocused image object planes almost free of Fixed-Pattern Noise (FPN) and blur artifacts. And, the capability of achieving multispectral LWIR imaging for the global scene and for all the refocused nearby object planes required, this is, LWIR radiometry refocusing capacity. The built-in LWIR LF imaging system is implemented with an LWIR microbolometer Xenics camera 8-12 micrometers spectral band, and a high precision scanning system(Newport). LWIR multispectral capacity is achieved with an array of narrow-band LWIR interference optical filters.
